Drop-in S3-compatible backend for object storage (media + email attachments) —
the swap the StoragePort seam was designed for. MinIO/self-hosted/R2/Supabase all
work via endpoint + path-style.
- S3Storage implements StoragePort (put/get/remove); sha256 computed locally on put
(matches LocalDiskStorage); a missing object reads back as null, not an error.
- Env-driven binding in MediaModule: IIOS_S3_BUCKET + keys set → S3Storage, else
LocalDiskStorage. forcePathStyle defaults true (MinIO); endpoint omitted → AWS.
- S3 client is injectable so tests run with no live server.
6 unit tests (config parse, put size/sha, get round-trip, NoSuchKey→null, remove).
Full suite 300/300, boundary + build clean.

Email can now carry attachments (e.g. an invoice PDF). The kernel already stored
attachments as message parts + the media StoragePort holds the bytes; the gap was
the email envelope.
- EMAIL payload carries attachment REFS ({filename, contentRef, mimeType}), not
bytes — the ledger + T8 PII redaction stay small; bytes are fetched at send time.
- SmtpProvider takes an AttachmentResolver; resolves each ref via storage and attaches
(nodemailer). FAILS CLOSED if a declared attachment can't be resolved (or no resolver
is wired) — never send a receipt/invoice missing its file; a FAILED command retries.
- CapabilityProviderRegistry injects the resolver from STORAGE_PORT (@Optional);
MediaModule exports STORAGE_PORT, CapabilityModule imports MediaModule. No cycle.
- TemplatedSender + MailService + the /v1/mail/send DTO pass attachments through.
Verified: 6 new unit tests (attach, fail-closed x2, plain-unaffected, resolver,
pass-through) + a REAL Ethereal SMTP send WITH a PDF attachment (SENT). Full suite
294/294, boundary + build clean.

Media the industry way: the DB stores a reference, bytes live behind a storage port.
- StoragePort + LocalDiskStorage (dev). MediaService presigns short-lived signed
upload/download URLs (HS256 tokens) pointing at IIOS's own endpoints; the bytes
never touch the kernel. Prod swaps STORAGE_PORT to S3/Supabase — same as auth.
- MediaController: presign-upload / PUT upload/:token (raw stream) / GET blob/:token /
presign-download. Uploads are OPA-governed (iios.media.upload: 25 MB cap +
image/video/audio/pdf/office allowlist); downloads are tenant-fenced by object key.
- send() + MessageDto carry an attachment (contentRef/mimeType/sizeBytes → generic
MEDIA_REF/VOICE_REF/FILE_REF part; DTO exposes kind image|video|audio|file).
Tests: media.service.spec (6) — round-trip, oversize/type denied, oversized PUT
refused, tampered token rejected, tenant fence. Full suite 192 green. Verified live:
presign→upload→send→history→signed download round-trips the exact bytes.
